j I IMPROVEMENT IN SOIL-PU-LVERIZERS.

Specification forming part of Letters Patent No. 196,617, dated October 30, 1877 application filed March 21, 1876.

To all 'whom/t may concern:

Be it known that I, JEssE .ADAMs, of the town of Lewisville, county of Henry, and

rState oflndiana, have invented certain new tion. Fig. 2 4is a longitudinal sectional view thereof. j

The object of my invention is to provide an efficient means of pulverizing the soil, and of cutting up, to a degree of iineness that will not interfere with the free cultivation of the field, all corn-stalks, stubble, or other litter that may encumber the ground. This is acj complished by a machine constructed for that 4 purpose.

In the drawings, AV and B represent the wheels on which my machine runs. N is the frame, which is pivoted on the axle P. C is a ratchet-wheel keyed fast to the shaft oraxle P. D is a pawl which engages in said wheel (l, and which is heldin place by thespring E. F and Gare cylinders from which project the teeth H H. I I are sickle-shaped knives, which project from the bars J J. K is a gearwheel on axle l?. L is a gear-wheelon cylinder F. M is a gear-wheel on cylinder Gr. Q Q are standards, to which is attached the pole for the team. R R are pins in said standards, by which the pole is raised or lowered and the distance to which the teeth-H H shall enter into the ground regulated.

The operation of my invention is as follows: The machine is drawn ahead by the tongue or pole S. The traction, of course, revolves the wheel A, which, by means of the catch D and ratchet-wheel G, revolves the shaft l?, which carries the gear-wheel K. This, in turn, drives gear-wheel L, which drives gear-wheel M, making the cylinders F and Gr revolve toward each other, and the teeth H H are thereby driven into the ground. Said teeth not only pulverize the soil by their action, but catch up stubble, vines, corn-stalks, or any other description of litter, and force it against the knives I I, and cut it to a degree of ineness so that it will not interfere with further cultivation, and mix it with the earth, so that it will rot and become of use as a fertilizer.

If desired, the catch D can be disconnected and the cylinders F G made fast, when the machine will act simply as a harrow.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

In a machine for pulverizing the soil, the combination of the frame N, pivoted on the axle, the adjustable draft-pole S, and standards Q Q with cylinders F and G, having teeth H H, and bars J J, having knives I I, substantially as herein shown and described.
